PsrLogger

API reference › yii › log › PsrLogger

final class	yii\log\PsrLogger
Extends	Psr\Log\AbstractLogger
Since	22.0
Source	framework/log/PsrLogger.php

Adapts PSR-3 log calls to a Yii logger.

When no Yii logger is passed to the constructor, the current logger returned by Yii::getLogger() is resolved for every call. This ensures that replacing the global Yii logger does not leave this adapter with a stale reference.
